Typedefs

typedef uint8_t RAIL_TxPowerLevel_t
Raw power levels used directly by the RAIL_Get/SetTxPower API where a higher numerical value corresponds to a higher output power.

Enumerations

enum RAIL_TxPowerMode_t {
RAIL_TX_POWER_MODE_2P4_HP ,
RAIL_TX_POWER_MODE_2P4_LP ,
RAIL_TX_POWER_MODE_SUBGIG ,
RAIL_TX_POWER_MODE_NONE
}
An enumeration of the EFR32 power modes.

Detailed Description

Types specific to the EFR32 for dealing with the on-chip PAs.

Typedef Documentation

typedef uint8_t RAIL_TxPowerLevel_t

Raw power levels used directly by the RAIL_Get/SetTxPower API where a higher numerical value corresponds to a higher output power.

These are referred to as 'raw (values/units)'. On EFR32, they can range from one of RAIL_TX_POWER_LEVEL_LP_MIN , RAIL_TX_POWER_LEVEL_HP_MIN , or RAIL_TX_POWER_LEVEL_SUBGIG_MIN to one of RAIL_TX_POWER_LEVEL_LP_MAX , RAIL_TX_POWER_LEVEL_HP_MAX , and RAIL_TX_POWER_LEVEL_SUBGIG_MAX , respectively, depending on the selected RAIL_TxPowerMode_t .

Enumeration Type Documentation

enum RAIL_TxPowerMode_t

An enumeration of the EFR32 power modes.

The power modes on the EFR32 correspond to the different on-chip PAs that are available. For more information about the power and performance characteristics of a given amplifier, see the data sheet.
